I've had the GS7 Edge since April or so. It is a very sexy phone. The battery is pretty good and I appreciate the water resistance.
Is it delicate? Well anything that you sammich with 2 pieces of glass is going to be fragile. The spousal unit has cracked 2 regular Galaxy S7s. I've had mine in a clear TPU case for most of it's life and have flung it to the ground a few times in stupors with no ill effect.
I believe it is a worthy upgrade from a GS5 in a lot of ways, not least of which timely security patches. My t-mobile GS7e has been receiving regular monthly security software updates. I also upgraded to it from the Note 5 and found it runs smoother and doesn't get as warm when chugging along with multiple apps/games/navigation/music all going on.
Since you have a GS5 Active I bet your'e on AT&T. Have you considered the Galaxy S7 Active? It's still water resistant but also buttugly shock resistant too.
I'm really hoping the Note 7 gets back in stock soon because that was going to be my next upgrade. It seems to be a bigger GS7edge with a stylus. Even though I didn't use the stylus much I still liked it for a few things like selecting text on pages that for whatever reason didn't allow the native text select thing (like google hangouts...why can't I just select some text from a SMS?!?!)
